Zero to Sixty by Marie Harte

After her last relationship bombed, Ivy Stephens is doing her best to put her life back together. She’s enjoying her job, her apartment-and the cute little puppy she’s seen hanging around. When she goes looking for him, she finds the stray in the arms of a big, burly, devastatingly handsome man.

Sam Hamilton is lonelier than he’s ever been after his best friend’s engagement. To give himself a sense of purpose, he takes in a puppy that keeps showing up around the garage where he works. The puppy has another suitor though-one who happens to be blond and beautiful.
